Mr. Data Converter
Mr. Data Converter has sufficient features to successfully convert CSV to JSON file. It has a left section and the rest of the part of its interface is reserved to view input CSV and output JSON data. You can also edit CSV and JSON file data which is a good feature. Apart from CSV to JSON, you can use it to convert CSV to PHP, XML, HTML, and more. This is an advantage of this website over other online CSV to JSON converters.
Using its left section, you can set delimiter (auto, comma, and tab), decimal sign (dot or comma), set the first row as header, include/exclude space in output, etc. Based on the set options, the output is generated. This website doesn’t support feature to upload CSV file and download JSON file. It lets you paste CSV data and copy output JSON data to the clipboard. But, the output comes as expected. So, the website is good to use.
These are my best picked online CSV to JSON converters. Each CSV to JSON website is good enough to give the expected output. Still, my favorite is “Code Beautify” website on this list. And when you have to convert large CSV files, then I will recommend you #2 website available on this list.
